What size is spare on r/t?

I'm looking at 22s but will be towing a racecar and want a full-size spare if I'm going cross country

Thanks. Can you crawl underneath and look sometime? I imagine you can run a smaller tire on one corner for a while although I worry the traction control/ ABS/computer might throw some codes or put you in limp mode?

265/50-20 = 30.43 OD & 245/65-18 = 30.54 OD so their very close!
